Objectives: Concussions affect the processing of emotional stimuli. This study aimed to investigate how sex interacts with concussion effects on early event-related brain potentials (ERP) measures (P1, N1) of emotional facial expressions (EFE) processing in asymptomatic, multi-concussion athletes during an EFE identification task. Methods: Forty control athletes (20 females and 20 males) and 43 multi-concussed athletes (22 females and 21 males), recruited more than 3 months after their last concussion, were tested. Participants completed the Beck Depression Inventory II, the Beck Anxiety Inventory, the Post-Concussion Symptom Scale, and an Emotional Facial Expression Identification Task. Pictures of male and female faces expressing neutral, angry, and happy emotions were randomly presented and the emotion depicted had to be identified as fast as possible during EEG acquisition. Results: Relative to controls, concussed athletes of both sex exhibited a significant suppression of P1 amplitude recorded from the dominant right hemisphere while performing the emotional face expression identification task. The present study also highlighted a sex-specific suppression of the N1 component amplitude after concussion which affected male athletes. Conclusions: These findings suggest that repeated concussions alter the typical pattern of right-hemisphere response dominance to EFE in early stages of EFE processing and that the neurophysiological mechanisms underlying the processing of emotional stimuli are distinctively affected across sex.

“…Similar findings related to persistent changes in the P3a component have been reported in previously concussed participants 22 to 60 months [60], 3.4 years [8], and 26 years [15] post-injury. To a lesser extent, suppressed Ne has been shown at 2.9 years [47], suppressed P1 amplitude at 6.7 years [45], and an altered N2 component at 7.1 years post-injury [46]. While these findings were generated in response to the target stimuli during a visual task, compared to the auditory task implemented here, it is possible that ongoing deficits may need to be accounted for by clinicians when interpreting post-concussion results.…”

Investigating a Novel Measure of Brain Networking Following Sports Concussion

Clinicians managing sports-related concussions are left to their clinical judgment in making diagnoses and return-to-play decisions. This study was designed to evaluate the utility of a novel measure of functional brain networking for concussion management. 24 athletes with acutely diagnosed concussion and 21 control participants were evaluated in a research laboratory. At each of the 4 post-injury time points, participants completed the Axon assessment of neurocognitive function, a self-report symptom inventory, and the auditory oddball and go/no-go tasks while electroencephalogram (EEG) readings were recorded. Brain Network Activation (BNA) scores were calculated from EEG data related to the auditory oddball and go/no-go tasks. BNA scores were unable to differentiate between the concussed and control groups or by self-report symptom severity. These findings conflict with previous work implementing electrophysiological assessments in concussed athletes, suggesting that BNA requires additional investigation and refinement before clinical implementation.

“…Moreover, by eliminating upper body injuries from the analysis, we eliminated the chance of a concussion being misclassified as an upper body orthopaedic injury. Lower body injuries are the most common musculoskeletal injuries in ice hockey, 13 so limiting the orthopaedic injury group to lower body injuries made that group more homogeneous while it continued to represent NHL orthopaedic injuries. Finally, classifying a concussive injury as an upper body injury may result in underreporting 31 or missing these injuries, which would also limit our ability to assess all concussive injuries.…”

“…7 In general, recovery to preinjury levels of functioning is spontaneous, with symptom resolution within days to weeks postinjury. 8 However, authors of recent laboratory studies have indicated that subtle deficits persisted in measures of gait and balance, 9 dynamic motor tasks, 10 working memory, 11 reaction time, 12 visual processing, 13 and cognition, 14 even after concussion-related symptoms resolved.…”

“…Movement skill requires the simultaneous execution of cognitive and motor processes that are critical in athletics, and concussion-related decrements in sensory processing, 13 error processing, 15 gait, 9 and attention 16 can potentially disrupt the effective execution of these skills. However, research examining the effects of concussion on subsequent athlete performance has generated mixed results.…”

Context Concussions elicit changes in brain function that may extend well beyond clinical symptom recovery. Whether these changes produce meaningful deficits outside the laboratory environment is unclear. The results of player performance postconcussion within professional sports have been mixed. Objective To determine whether National Hockey League (NHL) players with concussions performed worse after returning to sport than players with lower body injuries or uninjured players. Design Cohort study. Setting Publicly available Web sites that compiled injury and player statistics of NHL players. Patients or Other Participants Male NHL players who missed games due to a concussion (n = 22), lower body injury (n = 21), or noninjury (ie, personal reason or season break; n = 13) during the 2013–2014 and 2014–2015 regular seasons. Data on concussed athletes were used to identify similar players with lower body injury and noninjury based on (1) position, (2) time loss, (3) time on the ice, and (4) team. Main Outcome Measure(s) The primary performance metric was a modified plus-minus statistic calculated by weighting the players' plus-minus metric by their team's simple rating system to account for varying team performances. Linear mixed models assessed the relationship between injury type (concussion, lower body, or noninjury) and performance (plus-minus score). Results We observed a quadratic effect for a time2 × group interaction (\upchi _2^2 = 8.85, P = .01). This interaction revealed that the concussion and lower body injury groups had similar patterns of an initial decrease (ie, 2 weeks after return to play), followed by an increase in performance compared with the uninjured group in weeks 5 and 6. Meanwhile, the uninjured group had an initial increase in performance. We observed no group × linear time interaction (P = .47) or overall group effect (P = .57). Conclusions The NHL players in the concussion and lower body injury groups displayed similar performance impairments. Both injured cohorts experienced an initial decrease in performance at weeks 1 to 2 after return to play, followed by improved performance at weeks 5 to 6 after return to play, suggesting that the performance implications of concussion may be short lived.

Sport-Related Concussion and Sensory Function in Young Adults

Abstract: These results suggest that concussion history has a negative effect on visual processing in young adults. Further, upper-level neurocognitive deficits associated with concussion may, in part, result from less efficient downstream sensory capture.
